The grill in which the meat sits on inside the bbq is rusted from being out in the cold and rain.|||heat it up with a good flame & when hot, brush with a wire brush. Allow the flame ton continue burning for a few minutes after brushing. The flame will sufficiently sanitize the grill.|||Please replace it with new grill do not take risk it may be harmfully, it can not be cleaned 100% still some rust may retain, so Go in for New one.|||I think you should get one of those brushes that is metal i guess
